Abstract

This paper presents the observer based output feedback control design for linear systems which have both input and output time delay. Sufficient conditions for existence of stabilizing output feedback controller are characterized by linear matrix inequalities. Since the condition of the proposed design depends on the value of time delay, it is less conservative than existing delay-independent approaches. Finally, an illustrative example is given in order to show the effectiveness of our design method.

본 논문에서는 입력과 출력에 동시에 시간 지연이 존재하는 선형시스템에 대한 관측기 기반의 출력피드백 제어방법을 제안한다. 선형행렬 부등식을 이용하여 출력 피드백 안정화 제어기가 존재할 충분조건을 유도한다. 입출력 시간지연을 모두 고려했다는 점과 관측기 기반의 출력 피드백제어기 라는 점에서 기존의 연구결과와 차별성을 가진다. 마지막으로 제안한 결과의 유효성을 증명하기 위하여 모의실험 예제를 제공한다.
